9. Rising Sun

Billionaires have the same problems as the rest of us. Take Larry Ellison, CEO of Oracle: After buying his mega-yacht, the Rising Sun, he came to that all-too-common conclusion that it was just too big. Been there, done that.

At almost 453 feet long, Ellison should have known he wouldn't be able to dock it just anywhere, but that probably didn't matter. The important thing was that it was the longest when it was built. For a few months, anyway. Now it's new owner David Geffen's problem, a problem that includes nothing phenomenally outrageous, just a laundry list of impressive amenities. Amenities like a basketball court, eight staterooms, 82 rooms, a decorative stone wall that rises up through the middle of the yacht, a Jacuzzi, a wine cellar, glass and brushed-chrome staircases, a sitting room with a wood-burning fireplace, curved floor-to-ceiling windows lining two of the decks, and a crew of 30 to wait hand and foot on Geffen and guests.
